Render-to-Surface ignoring separate alpha blending?,

In order to do this I:
-Render the text to the surface
But I notice that this causes low-alpha texels around the edges of the rendered text, which is not good. So I try this:
-Create new texture with the dimensions of the existing one
-Render the text to it
-Start RTS on the original texture surface
-Draw the new surface on top of it
-Dispose of the 'temporary' surface
But I'm still getting the same problem.
I checked my render states and I have separate alpha blending enabled. The op is ADD and the src/dest are the src/dest alpha, but the problem remains.
D3DPMISCCAPS_SEPARATEALPHABLEND is true.
So all I can think of is that maybe RTS ignores separate alpha blending?
Has anyone else run into this kind of thing?
Thanks in advance for any advice.
